Cranial Neurosurgery

Dr Jonker offers expertise in cranial neurosurgery with a special interest in brain tumours, trigeminal neuralgia and functional neurosurgery, including Deep Brain Stimulation for Parkinson’s Disease and essential tremor.

Stereotactic Radiosurgery

Stereotactic radiosurgery is a minimally invasive technique developed by neurosurgeons to treat brain tumours, spine tumours and trigeminal neuralgia using highly focused radiation delivered precisely to the tumour.

Intraoperative MRI

iMRI is an advanced technology that allows scans to be performed during the operation for the goal of maximum safe tumour removal. Royal Prince Alfred Hospital is the only hospital in NSW with this technology.
